2. Figure 1
The positions of the perforators penetrating the lateral and medial heads of the gastrocnemius muscle from the soleus muscle were measured as a ratio using the distance between the fibula head and the perforating points and the distance between fibula head and lateral malleolus, and the ratio using the distance between the center of gastrocnemius muscles and the perforating points and the distance between the center of gastrocnemius muscles and lateral border of muscles. All perforators were marked on 16 cadavers. There was a high frequency of perforators on the margin. In all cases perforators was found distal half of the gastrocnemius muscle.

4. Figure 3
Angiography done in a fresh cadaver via the lateral sural artery after the soleus and gastrocnemius muscles were raised, confirmed that reversed flow could be seen from the external margin of the lateral head of the soleus muscle (underlined).
